Brief Summary:
This study is attached to a comprehensive quality assurance/quality improvement (QA/QI) program conducted by the Office of the medical director, and is designed to contribute to generalizable knowledge to determine effectiveness and tolerability of an FDA approved Impedance Threshold Device (ITD) device in a large urban emergency medical service (EMS) system. The cohort will comprise a convenience sample of patients that are being treated by EMS for a hypotensive emergency.

Arm Intervention/treatment
Experimental: ResQGARD ITD
Subjects receive a ResQGARD ITD.
Device: ResQGARD ITD
Patients eligible for the device will receive the ResQGARD attached to a facemask or mouthpiece. The patient will use the device, provided it is tolerated, until their blood pressure is stabilized as determined by EMS personnel.

Primary Outcome Measures :
  1. Change in Systolic Blood Pressure From Baseline (Before ITD Use) [ Time Frame: During device use, up to 1 hour ]
    Determining whether the application of an ITD will provide improvement in systolic blood pressure in subjects with hypotension in patients being treated by San Antonio EMS when compared to baseline.

Secondary Outcome Measures :
  1. Tolerability [ Time Frame: Duration of device use, up to 1 hour ]
    Determine patient tolerability of the device while breathing through it. This is subjectively measured by the paramedic administering the device based on verbal reporting from the patient and paramedic estimation of the patient response to the device.
